4 WAX-TH READ s EWING-MACHIN E.

SPECIFICATION forming part of Letters Patent No. 499,414, dated June 13,1893. Application filed March 23, 1893. Serial No. 467,230. (No model.)

' machines and to their adaptation for heating the wax thread andthereby keeping. it soft and pliable for its manipulation by theordinary or other suitable mechanism for making the stitches.

The invention, in substance, consists of a hollow shaft, havingmeans atits opposite end-portions, to confine against endwise movement a sleevecarrying the take-up arm of the machine, a detachable cap, suitable toclose said shaft at one end, and a detachable chambered nipple suitableto close said shaft at its other end, a steam escape pipe leading ofifrom one side of said nipple, in combination with a steam inlet pipeleading through said nipple and into and along, and of less diameterthan said hollow shaft, but open thereto and terminating therein near toits said cap closed end and, all so that steam properly entered into andthrough said inlet pipe is thereby entered into said shaft at its saidcap closed end and allowed thence to pass toward the opposite end ofsaid shaft there to escape through the escape steam pipe, the wholeresulting in securing the heating of said shaft, the take-up arm turningon it, and the wax thread carried and controlled by said arm as in themaking of the several stitches by the usual operation of said arm andthe other suitable stitch making devices of waxed thread sewingmachines.

In the drawings, forming part of this specification, Figure 1 is aperspective view of a wax thread sewing machine, the usual constructionof the' well known Goodyear wax thread sewing machines, except as thesame is varied by the contrivances of this invention. Fig. 2 is in parta transverse vertical section and side view of the stitch formingmechanism. Fig. 3 is an enlarged vertical, longitudinal, sectional view,line 3-3, Fig. 2, of the special features of this invention and otherparts in line therewith.

In the drawings,A represents the post or standard of the machinereferred to and carrying at its upper end portion the variousworkingparts for sewing purposes, using a wax thread, some of whichparts will be referred to by letter in order to distinguish them, whilethe same except as hereinafter particularly stated form no part of thisinvention.

B is the awl, and B is the awl arm. This awl arm is' oscillated througha connecting arm 13 connected at one end to it and at the other end to abell-crank B, by the movement of which the awl is properly oscillated asdesired. The awl-arm B works on a bracketprojection B of a horizontalslide B adapted 'to move on a guide-way B toward and away from one endof a fixed horizontal shaft 0, exteriorly surrounded by and making abearing for a sleeve D, carrying the take-up arm E, all so far as wellknown. Under this invention, however, 'said shaft 0 is hollow or tubularfrom end to end and at its end toward said awl-arm slide B it is closedby a detachable cap 0 at one side carrying a loose peripherally groovedthread-roller C beyond which isa fixed collar F on the tubular shaft 0followed by the sleeve D of the take-up-arm E, in turn followed byanother fixed collar F at the end 0 of the hollow shaft opposite to itsend closed by cap O as aforesaid. The

shaft end 0 has a chambered nipple O screwed or suitably attachedthereto, and,

from one side of which leads a steam escapepipe G as particularlyappears hereinafter.

H is a tube leading through the end of the nipple and thence along thelength of, but of less diameter than the hollow shaft 0, and terminatingnear its screw-capped end and there opening to its chamber J about andsurrounding the tube H and within the shaft 0. This tube H is for thepassage of steam and entering therefrom into the chamber of the tubularshaft near its cap closed end, to thence pass through the shaft to itsend connected with the steam escape-pipe G, to be, by it, conducted asmay be desired, as for instance, to the wax-pot. Steam entered into andpassing along the tubular shaft of the take-up arm all as describedsecures the heating of said shaft, said take-up arm and the threadcarried by said arm and to the most perfect and practical degree, and inthe most advantageous manner, all as is obvious, without particularmention.

Having thus described my invention, what I claim, and desire to secureby Letters Patent,is-

In a waxed thread sewing machine, in combination, the take-up-arm, asleeve forming part of said arm and rocking on a fixed hollow stationaryshaft, means confining said take-up arm against endwise movement on saidshaft, a cap closing one end and a thimble closing the other end of saidshaft, a steam inlet tube of less diameter and passing into, lengthwiseof, and opening to said shaft, near one of its ends, and a steam escapetube in communication with the opposite and closed end of said hollowshaft, substantially as described, for the purpose specified.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

OTIS E. BROWN.
